Techniques for Implementing Information Services with Tenant Specific Service Level Agreements

1. A method for selecting an information service implementation, comprising: receiving, at a data processing system that functions as a shared interface for multiple tenants, a service request that includes a tenant identifier that uniquely identifies a calling tenant; selecting, by the data processing system, transformation logic provided by a specific virtual machine to service the service request based on the received tenant identifier to implement a tenant specific service level agreement for the calling tenant; selecting, by the data processing system, one or more data sources and one or more data targets for the service request based on the received tenant identifier to implement the tenant specific service level agreement for the calling tenant; processing, by the data processing system, data from the selected data sources using the selected transformation logic, wherein the selected transformation logic implements one or more algorithms that are used to transform the data; and storing, by the data processing system, the processed data at the selected data targets.

2. The method of claim 1 , wherein the tenant identifier corresponds to a user identifier, a user password, a security token, or a certificate.

3. The method of claim 1 , wherein the tenant identifier is derived from a payload or context of the service request or a mapping of a user to the calling tenant.

4. The method of claim 1 , wherein the transformation logic to service the service request is selected at runtime.

5. The method of claim 1 , wherein the selecting, by the data processing system, transformation logic to service the service request based on the received tenant identifier further comprises: selecting, by the data processing system, a specific agent to process the service request based on the received tenant identifier.

6. The method of claim 1 , wherein the selecting, by the data processing system, one or more data sources and one or more data targets for the service request based on the received tenant identifier further comprises: selecting, by the data processing system, one of a shared database for multiple tenants, a shared database with separate schemas for different tenants, or a shared database with shared schema for multiple tenants for the service request based on the received tenant identifier.

7. The method of claim 1 , wherein the selecting, by the data processing system, one or more data sources and one or more data targets for the service request based on the received tenant identifier further comprises: selecting, by the data processing system, one of a shared database for multiple tenants, a shared database with separate schemas for different tenants, or a shared database with shared schema for multiple tenants for the service request based on the received tenant identifier and a service level agreement for the calling tenant.

8. A computer program product for selecting an information service implementation, the computer program product comprising: a computer-readable storage device having computer-readable program code embodied thereon, wherein the computer-readable program code, when executed by a data processing system that functions as a shared interface for multiple tenants, causes the data processing system to: receive a service request that includes a tenant identifier that uniquely identifies a calling tenant; select transformation logic provided by a specific virtual machine to service the service request based on the received tenant identifier to implement a tenant specific service level agreement for the calling tenant; select one or more data sources and one or more data targets for the service request based on the received tenant identifier to implement the tenant specific service level agreement for the calling tenant; process data from the selected data sources using the selected transformation logic, wherein the selected transformation logic implements one or more algorithms that are used to transform the data; and store the processed data at the selected data targets.

9. The computer program product of claim 8 , wherein the tenant identifier corresponds to a user identifier, a user password, a web services security (WSS) token, or a certificate.

10. The computer program product of claim 8 , wherein the tenant identifier is derived from a payload or context of the service request or a mapping of a user to the calling tenant.

11. The computer program product of claim 8 , wherein the transformation logic to service the service request is selected at runtime.

12. The computer program product of claim 8 , wherein the computer-readable program code, when executed by a data processing system, further causes the data processing system to: select a specific agent to process the service request based on the received tenant identifier.

13. The computer program product of claim 8 , wherein the computer-readable program code, when executed by a data processing system, further causes the data processing system to: select one of a shared database for multiple tenants, a shared database with separate schemas for different tenants, or a shared database with shared schema for multiple tenants for the service request based on the received tenant identifier.

14. The computer program product of claim 8 , wherein the computer-readable program code, when executed by a data processing system, further causes the data processing system to: select one of a shared database for multiple tenants, a shared database with separate schemas for different tenants, or a shared database with shared schema for multiple tenants for the service request based on the received tenant identifier and a service level agreement for the calling tenant.

15. A data processing system that functions as a shared interface for multiple tenants, comprising: a memory; and a processor core coupled to the memory, wherein the processor core is configured to: receive a service request that includes a tenant identifier that uniquely identifies a calling tenant; select transformation logic provided by a specific virtual machine to service the service request based on the received tenant identifier to implement a tenant specific service level agreement for the calling tenant; select one or more data sources and one or more data targets for the service request based on the received tenant identifier to implement the tenant specific service level agreement for the calling tenant; process data from the selected data sources using the selected transformation logic, wherein the selected transformation logic implements one or more algorithms that are used to transform the data; and store the processed data at the selected data targets.

16. The data processing system of claim 15 , wherein the tenant identifier corresponds to a user identifier, a user password, a web services security (WSS) token, or a certificate.

17. The data processing system of claim 15 , wherein the tenant identifier is derived from a payload or context of the service request or a mapping of a user to the calling tenant.

18. The data processing system of claim 15 , wherein the transformation logic to service the service request is selected at runtime.

19. The data processing system of claim 15 , wherein the processor core is further configured to: select a specific agent to process the service request based on the received tenant identifier.

20. The data processing system of claim 15 , wherein the processor core is further configured to: select one of a shared database for multiple tenants, a shared database with separate schemas for different tenants, or a shared database with shared schema for multiple tenants for the service request based on the received tenant identifier and a service level agreement for the calling tenant.
